Good morning, commuters! We’ll be keeping an eye on the roads and rails this morning, reporting any delays or issues — and we will need your help. If you hear about any congestion, delays, problems or anything at all, tell us in the comments section below or by tweeting @drgridlock.

There will be a bit in the way of clouds and patchy fog this morning, according to the Capital Weather Gang. And in some areas, the roadways could still be slick and wet after Wednesday’s snow and rain, so watch out for that.

So far:

— An accident on westbound U.S. 50 after Martin Luther King Jr. Highway/MD 704 is locking all of the main lanes. Traffic only gets by on the shoulders. This is just east of where U.S. 50 hits the Beltway in Maryland.

— An accident on I-95 North at the Fairfax County Parkway is blocking the right two lanes and the right shoulder.

— A disabled vehicle on the outer loop of the Beltway after the G.W. Parkway is blocking the right shoulder.
